C# socket.isConnected返回false

我正在写一个pc和电话通讯应用程序。pc代码是用C#编写的。当我将手机（与pc配对）连接到pc时，手机会连接，但日志显示，插座未连接I-e；socket.isConnected（）在我的手机上返回false。我尝试在多部手机上运行此应用程序，但问题仍然存在

我认为问题在于我的C代码，因为我对C不太了解

以下是c代码：

        BluetoothListener blueListener = new BluetoothListener(mUUID);
        blueListener.Start();


        BluetoothClient conn = blueListener.AcceptBluetoothClient();

        if(conn.Connected)
            updateUI("Mobile connected");


        Stream mStream = conn.GetStream();
        while (true)
        {
            try
            {
                byte[] received = new byte[1024];
                mStream.Read(received, 0, received.Length);
                //.....
            }
            catch() {}
        }

BluetoothSocket socket = selectedDevice.createRfcommSocketToServiceRecord(deviceUUID);
try
    {
        socket = openSocketForSendingData();

        try
        {
            BluetoothAdapter bAdapter = BluetoothAdapter.getDefaultAdapter();

            bAdapter.cancelDiscovery();
            socket.connect();

            Log.e("NP socket", "No Exception");
        }
        catch(Exception e)
        {
            Log.e("NP socket Exception", e.toString());
        }


        if(socket == null)
            Log.e("Socket NULL", "socket is null");


        if(!socket.isConnected())
        {
            Log.e("NP socket", "socket not cconnected");

            try
            {
                socket.close();
            }
            catch(Exception e)
            {
                Log.e("Socket CLOSE",e.toString());
            }

        }
        else
            Log.e("NP socket", "socket  cconnected");   

        if(socket.getOutputStream() == null)
            Log.e("Soccket Outupt", "output stream null");  

        dos = new DataOutputStream(socket.getOutputStream());

        dos.writeChars("Hello World I am android");

    }
    catch(Exception e)
    {
        Log.e("NP writing socket", e.toString());   
    }

我正在使用C#中的32英尺库

以下是我的Android代码：

        BluetoothListener blueListener = new BluetoothListener(mUUID);
        blueListener.Start();


        BluetoothClient conn = blueListener.AcceptBluetoothClient();

        if(conn.Connected)
            updateUI("Mobile connected");


        Stream mStream = conn.GetStream();
        while (true)
        {
            try
            {
                byte[] received = new byte[1024];
                mStream.Read(received, 0, received.Length);
                //.....
            }
            catch() {}
        }

BluetoothSocket socket = selectedDevice.createRfcommSocketToServiceRecord(deviceUUID);
try
    {
        socket = openSocketForSendingData();

        try
        {
            BluetoothAdapter bAdapter = BluetoothAdapter.getDefaultAdapter();

            bAdapter.cancelDiscovery();
            socket.connect();

            Log.e("NP socket", "No Exception");
        }
        catch(Exception e)
        {
            Log.e("NP socket Exception", e.toString());
        }


        if(socket == null)
            Log.e("Socket NULL", "socket is null");


        if(!socket.isConnected())
        {
            Log.e("NP socket", "socket not cconnected");

            try
            {
                socket.close();
            }
            catch(Exception e)
            {
                Log.e("Socket CLOSE",e.toString());
            }

        }
        else
            Log.e("NP socket", "socket  cconnected");   

        if(socket.getOutputStream() == null)
            Log.e("Soccket Outupt", "output stream null");  

        dos = new DataOutputStream(socket.getOutputStream());

        dos.writeChars("Hello World I am android");

    }
    catch(Exception e)
    {
        Log.e("NP writing socket", e.toString());   
    }

两个代码中的UUID相同

你能告诉我我犯了什么错误吗

附言：在问这个问题之前，我已经花了一整天的时间在互联网上搜索解决方案，但是没有用

您是否能够解决该问题？
